    71X Series Calibration Manual Pressure Measure The 718 Pressure Calibrators have built-in temperature compensation. Instruments being calibrated should be in a stable temperature environment for several minutes before calibration. Calibration facilities should be maintained near 23 °C nominal. Re-calibration (re-characterization) is performed in terms of ‘PSI’ pressure units. Inputs using other pressure units (ie.
